Specification of Letters Patent.

Application filed March 18, 1909.

Patented Jan. 4, 1910.

Serial No. 484,087.

T 0 all whom it may concern:

Be it known that I, ANGELO MANNELLO, a subject of the King of Italy, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Mandolin, ofwhich the following is a full, clear, and exact description.

The invention is an improvement in mandolins, having for its purpose toimprove the tone of the instrument and render the notes clear anddistinct. I have discovered that a mandolin securing these advantages isproduced by constructing the body oi the instrument of two cases, aninner case and an outer case respectively, both cases being ofsubstantially the same shape and spaced from each other at both thesides and bottom, the inner case preferably having a number of openingsin the bottom for the escape of the sound waves.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of ref erence indicatecorresponding parts in both views.

Figure 1 is a plan of a mandolin constructed in accordance with myinvention;

and Fig. 2 is an edge view of the same, partly in central longitudinalsection.

The body portion of the instrument is constructed of two cases, an innercase 5 and an outer case 6, both being of the same general form andspaced apart at both the sides and bottom. The belly 5 of the instrumentseats on the edge of and entirely covers the inner case 5 and isarranged in substantially the plane of the top edge of the outer case 6.The two cases are permanently secured together in spaced relation ateach side and ateach end, the connection between the cases at the sidesbeing effected by screws 7 passing from the outer case into the innercase and through spacing buttons 8 arranged in the intermediate groove.At the outer end of the body of the mandolin the two cases are securedtogether by, a screw 9 passing through a spacingblock 10. Both cases oithe mandolin body are rigidly connected to the sh ulder 12 of the neck.The connection between the shoulder 12 of the neck and the two cases oithe mandolin body, is rendered secure by the block 18, arranged withinand conforming to the inner end portion of the inner case. In the bottomoi the inner case near its inner end portion are formed a number ofholes 14: for the escape of the sound waves into the space between thetwo cases.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. in a musical instrument, a body comprising two cases arranged onewithin the oth r and spaced apart at the sides and bottom, with the topof the inner case having a belly and arranged in substantially the sameplane as the top edge or the outer case, spacing buttons arrangedbetween the two cases at opposite sides of the mandolin, means passingthrough the spacing buttons, joining the two cases together, and meanssecuring the cases together at opposite ends.

2. A mandolin having a body comprising an inner and outer case securedtogether and spaced apart at the sides, the body having a belly arrangedatthe top of both cases and sealing the top or the inner case.

A mandolin having a body comprising an inner and outer case securedtogether and spaced apart at the bottom and sides, the bottom oi theinner case perforated and the body having a belly closing the top of theinner case.

In. testimony whereol. I have signed my name to this specification inthe presence of two subscribing witnesses.

ANGELO MANNELLO.
